In some areas of the country, a consumer can install a windmill that generates electricity and sell that electricity to the utility (which then sells it to other consumers). If there were hundreds of individuals in an area, each with a windmill generating electricity, how would the utility handle the fact that each windmill generates AC electricity that is not in phase with the electricity generated by the other windmills?

I understand that there are methods for "shifting" the phase of AC electricity. But would each windmill have its own phase shifter, in order to provide "in-phase" electricity to the system? Or could each windmill sense the phase of the system and generate its electricity in phase?

Please help me understand how this works.
Thanks.

I need a way to get 5 mA of DC power at 9 volts out of 25 A of DC power at 12 volts. Can I just run leads off of it and use 3.1V Zener diodes or will the current blow them out? If so, how can I do this?

The rainwater will flow through the slopes to get under the floor and produce upthrust. It may rupture the floor.
